Rules
Back Rank Goblin
Deliver a back-rank mate with maximum goblin energy.
The escape square was a myth.
Classic chess punishment, but wearing a tiny goblin hat.

Funny, but rule-clear.
Trap the enemy king behind its own pieces and finish the game with a back-rank mate.
- You must win the game.
- The final position must be a back-rank checkmate pattern.
- The losing king should be trapped on its home rank or equivalent back-rank edge by its own pieces or blocked escape squares.
- Game must be public and played after this Side Quest is picked.
